Dig it up and check out the roots and soil. Then get back to us. How big was the tree?

Well my tree was around 4 feet tall and the roots are dead dry, found out that the husband forgot to water my baby the entire 23 days that I was gone! And it has been hot out here and no rain, according to my neighbor my tree died of thirst and heat.So now I am going to plant a plumeria there instead.

Sounds about right. I gave a fellow I work with a Montezuma cypress (farely rare) I'd grow from a seedling into a 4 foot tree. A couple years later I asked the guy how it's doin, he said "Oh, it died". I asked him how that happened. He said "I told my boy to water it, and he never did". Plumerias will struggle without regular water and good drainage, and they don't like frost.
